Everything surrounding the dart synthesis and gun creation was very collaborative. After the first 72 synthesis found by Martin Grant, Chris Cain found a reduction to 62 gliders. The first dart gun was created by Michael Simkin based on Martin Grant's synthesis. There followed another major reduction to 39 gliders by Martin Grant. Michael Simkin suggested a different way to synthesize the tail, while Tanner Jacobi found a particular way to reduce the synthesis to 35 gliders using Michael Simkin's method. Chris Cain suggested a way to reduce the front synthesis, which Michael Simkin implemented to reduce the synthesis to 28 gliders. Meanwhile Ivan Fomichev found a tricky way to save two gliders in Tanner Jacobi's recipe for the tail, and Michael Simkin found a way to remove another glider from the front, reducing the cost to 25 gliders.

After that, further attempts were made to create a dart gun. The first P160 gun was made by Martin Grant, while Alexey Nigin constructed a smaller P210 gun. Two more guns were made, one by Michael Simkin, the other (smaller one) by Dave Greene. Finally Chris Cain built the smallest P160 gun known today.
